Abstract [en]

Several previous contributions have proposed calculation methods that can be used to calculate the steady state (and from it the blocking probabilities) in CDMA systems. To our best knowledge, this present work is the first one that extends the classical Kaufman-Roberts formula such that it becomes applicable in CDMA where elastic services (with state dependent instantaneous bit rate and average bit rate dependent residency time) are supported. The core of this method is to approximate the original irreversible Markov chain with a reversible one and to assign a proper blocking measure to the macro states of the system.
